The main objectsofniy'invention are to reduce machining and assemblingof the brake cylinderstructure and thesaddle mem- T "her" on which theyare mounted}. to avoid the'necessity of frequent inspection and'tight Iening of brake cylinder mounting elements;

a systems. I r r g V r -r I attain these obje'cts by forming one or centportion of the the saddle, boiler support, main steam cylin- 1 tosimplify the to require repairs. Another-object is toform a fluidWayintegral withthe and saddle structure. I k I I Iihave developed myinvention with special attention to other forms of pneumatic orhydraulic; brake more brake cylinder elements integrally with thelocomotive saddle structure which forms a transverse brace for thelocomotive underframe and this structure can also carry the steamcylinders and'the smoke-boxor'adja boiler shelL, Preferably,

Steam cylinders and the rear vertical wall 2 of the saddle is apart of brake cylinder bodies 9 formed integrally therewith andprojecting from the wall with their axes disposed horizontally and thewall 2 of the saddle forming the inner ends or heads of the cylinderbodies 9. The outer ends or heads 10 of the cylinder bodies are formedseparately and secured to the cylinder body side walls by studs, bolts01 weldin".

The saddle wall 2 is recessed as indicated at 11 to provide an airpassage from a supply pipe 12 at the side of the cylinder body 9 to theinterior of the body and the wall is similarly recessed at 13 to providean air passage between the adjacent brake cylinder bodies 9.

A bushing 59 is preferably inserted in the cylinder so as to providerenewable means for wear on the interior of cylinder walls.

A saddle of this type may be readily cast in one piece and machined inthe usual boring machines and applied to the ordinary locomotive frameswithout special worl: on the latter.

In the construction shown. in Figures 4, 5 locomotive framing comprisesa box-shaped section having a bottom wall 14, side walls 15 and a topwall 16, and a saddle member extending transversely of the boxshapedsection 14l5-l5 and above the same 7 and including a front wall 17 and arear wall 19 and supply chambers 20 are integral with the framing andsaddle structure and the latter also includes an integral boiler support21. Projecting rearwardly from the rear wall 18 of the saddle structureare the curved walls 22 which merge with each other to form a commonpartition wall or web 21 and also merge with the wall 18 and cooperateto formhorizontallydisposed bral'ie cylinder bodies 23 having removablebushings 60 and removable non-pressure ends 24 provided with releasespring recesses 25. A projection F, integral with the 7 bottom wall 14:of the bed, provides a fulcrum for the mounting of the bralreleverindicated at L. Obviously, the relation between the same and brakecylinder body 23 will be maintained throughout the life of thelocomotive structure.

In this preferred construction, the parts specifically referred deck 95,the pilot beam 27, the valve gear support brackets 28, pedestals 29,etc. I prefer to f rm these parts by casting the same in one piece butit is practical to make some of the parts separate from each other bycasting or by any combination of the methods of casting, welding,forging, etc, and then unite them by welding. In any integral structure,whether formed by casting or welding or otherwise, the elimination ofattaching flanges, bolts or rivets, and the necessity of to are integralwith the entire locomotive bed which includes the front providing spacefor getting at the attaching elements for original installation or formain tenance or repairs, and the elimination of fitting of the parts fororiginal installation and the elimination of play between the parts, dueto wear and use, are some of the marked advantages which are not presentin the builtup structures previously used.

In the lnoditication illustrated in Figure 7, I show a sad lie '30having single air brake cylinder 31 formed integrally therewith with itsaxis disposed vertically and with both ends of the cylinder and 33,respectively, detachably mounted on the cylinder, the side wall of thecylinder being braced, by suitable ribs-B l, at points spaced from theupright wall of the sad le. This structure illustrates saddle applicableto the frames 35 of the locomotive and also shows the steam cylinders 36and supply chambers 3'? formed separately and applied to tae saddle inaccordance with a well-known practice.

In Figures 8, 9 and 10, I show a pair of air brake cylinders 38 disposedvertically, and mounted at points spaced from the saddle wall 39 bymeans of brackets lO provided with recesses 4:1 for lightening the sameand facilitating the casting of the cylinders integrally with thesaddlestructure. The saddle is formed integrally with the longitudinal membersd2 of the bed and includes integral steam cylinders 4C3, supply chambers41 i and a boiler support d5. Exhaust passages 4t6 extend inwardly ofthe saddle outer walls and unite in a centrally disposed eX- haustHOZZlQ' l'I, similarly to the corresponding parts in the structure shownin Figure l. Both ends 418 of. cylinders 88 are removable, which may bedesirable under some manufacturing conditions or for other reasons. 7

In. Figure 11, I illustrate a detail of a very similar construction inwhich the non-pres sure head 49 of the cylinder 50 is formed integrallywith. the same and with the bracket 51 which unites the cylinder withthe saddle 5:2, but the pressure head 53 is removably applied to thecylinder 50 in the usual manner.

In Figures 12 and 13, fication particularly adapted for a three cylinderlocomotive which the space immediately under the boiler support 54 isnot available for mounting the brake cylinder due to the projectio withthe ..m cyli or In this structure, I provide a brake cylinder 56 beneaththe steam cylinder disposed on an incline similar to cylinder 55, theinner end 57 of the brake cylinder forming an intermediatewall or ribfor the saddle 58 and serving to brace the same and the lower wall ofthe steam cylinder 55.

In Figures 14 and 15, I illustrate another modification of the saddlestructure in which I illustrate a modiparts on or associated messes thecomplete saddle is formed in two halves 61 and 62, each of whichincludes a main steam cylinder 63, a steam supply chamber :i flOQA.locomotive saddle'member having a main' steam cylinder, a steam; supplychember, and: a. brake cylinder body, all formed.v integrally; t I

The saddlemembers are provided with flanges 67 for attachment to each other andwith suitable elements 68.for attachment tothe brace 69 of thelocomotive frame. Each of the saddle pressure head of the cylinder andthe side wall 71 of the cylinder is integral [with and projects from thesaddle wall 70. Clearly,

Ineach of the Figures 3,5 and 9, I illustrate the adjacent truckwheels,.brake lever, piston, release spring and connection rods, but itwill do not form any part of my present invention as they have long beenin common use and .1 illustrate them merely relative to the brakethey'are associated.

Various other'modifications of the details of the device and relativearrangementof the parts shown may be made without-departing from thespirit of my invention and I contemplate the exclusive use of suchvariations as come within the scope of myclaims.
